- The present invention relates generally cutting devices and particularly to cutting blades and assemblies useful for cutting various materials such as tape used in packaging operations.
- 2. Description of Related Art
- Packaging machines or assemblies for sealing filled packages such as bags are well known. Many of these machines fill a package through an open end and then seal the package with tape. To create an effective seal that will not lose its grip, the tape must be properly applied to the package. Generally, this involves cutting the tape to the desired length and applying it to the proper place on the package or applying the tape to the package and cutting it at a desired location. This is typically accomplished using a cutting knife or blade that shears the tape at the proper location as the machine applies the tape to the package.
- After the tape is applied, it is important that the tape remain stuck to the package until it is intentionally removed and that the tape not tear and disrupt the integrity of the seal until the package is intentionally opened. It is particularly important that the tape not tear or otherwise compromise the integrity of the seal while the package being handled, e.g., during manufacture, during transport to market, or by the consumer.
- There are a variety of cutting knives or blades that can be used to cut the tape used to seal or close the packages. Generally, known or standard knives used to cut the tape leave a serrated edge at the cut, typically at both ends of the tape that is cut using the knife. In some instances, the serrated tape edge contributes to a premature tearing (e.g., propagated tear) of the tape. This disrupts the integrity of the seal and leaves the package seal formed by the tape prone to rupture or breaking. There is, therefore, a need for new devices and methods for using tape to seal packages such that the tape that will not tear prematurely and lose the integrity of the tape seal.
- The present invention provides cutting blades suitable for cutting various materials such as tape used in packaging and cutting assemblies or bag sealing assemblies comprising the blades.

One or more of the plurality ofteeth 30 defines asharp tip 40, and one or more of the plurality ofteeth 30 defines aflat tip 50. As shown inFIG. 1 , a first set of a plurality of the teeth defining aflat tip 50 can be positioned on the support between a second set of a plurality of the teeth defining asharp tip 40 and a third set of a plurality of the teeth defining asharp tip 40. - The
teeth 30 defining asharp tip 40 can be any suitable size and shape featuring a pointed or sharp edged configuration at the tip. Theteeth 30 defining aflat tip 50 can be any suitable size or shape featuring a flat or blunt tip. The surface of theflat tip 50 can have any suitable area and any suitably shaped perimeter. The distance between the top of theteeth 30 defining asharp tip 40 and the top of theteeth 30 defining a flat tip 50 (i.e. “F” as shown inFIG. 4 ) can be any suitable distance. - In an embodiment, the
flat tip 50 of theteeth 30 defines a rough surface. For example, the flat tip can have a surface that is course or uneven (e.g. not smooth) when felt. In another embodiment, theflat tip 50 of theteeth 30 defines a smooth or even surface. Flat tip, as used herein, means that the tip can be flat or that the tip can have a rough or uneven surface. For example, the flat tip could be slightly concave or convex or could have a wavy shape. In one embodiment, when the flat tip portion of the blade is not even with the sharp tip portion of the blade, the flat has a surface with cutting edges that are the same or similar to those of the sharp tip. - The
blade 10 can comprise a material such as a metal, a rigid plastic or combinations thereof. Theblade 10 can comprise a single unitary piece (e.g. a single molded piece) or can comprise separate components such as teeth that are attached or sealed to the support. - In an embodiment, the
support 20 defines one ormore aperture 60. Theapertures 60 can be any suitable shape and size, for example, that allows theblade 10 to be incorporated into any suitable device for holding the blade, e.g., a cutting or bag sealing assembly. - In an alternative embodiment, the first set comprises 15 teeth defining a
flat tip 50. The second set and third set of teeth having asharp tip 40 can each comprise 4½ teeth. For example, the blade can incorporate a design whereby four and one half (4½) outer teeth on both blade edges remain, and the center area of the cutting edge has the serrations (e.g. tips) removed. During tape cutting, it has surprisingly been found that this flat, non-cutting area of the blade can force the tape cut by the blade to “break” in a straight line and not leave any serrated edges to the tape seal. As a result, the edges of the tape that have been cut with a straight line have an improved strength over a cut tape having serrated edges. This improved strength results in less tearing of the tape when the tape has been attached to and used to seal off a package or container. - In yet another embodiment, the dimensions of the blade can be specified as illustrated in
FIG. 4 . For example, a length A1 of the second set of teeth added to a length A2 of the third set of teeth having a sharp tip can comprise a combined length that ranges from about 15% to about 40% of the length of the support L. In other words, the length A1 of the second set of teeth and the length A2 third set of teeth having a sharp tip are considered together in comparison to the overall length L of thesupport 20. In another embodiment, the length A1 of the second set ofteeth 40 and length A2 of the third set ofteeth 40 comprises a combined length that is about 20% of the length L of thesupport 20. - In still another embodiment, a difference in height F between the first set of teeth and the second set of teeth ranges from about 5% to about 22.8% of a height D of the
blade 10. In another embodiment, the difference in height F between the first set of teeth and the second set of teeth is about 7.4% of the height D of theblade 10. The height C of the first set of teeth and the second set of teeth can be about 22.8% of the height D of the blade. - The blade can have any suitable length, height and thickness so as to fit in any device suitable for holding the blade, e.g., a cutting or bag sealing assembly. In an embodiment, the blade comprises a length of about 2.5 inches. In another embodiment, the blade comprises a height of about 1.6 inches. In yet another embodiment, the blade comprises a thickness of about 0.065 inches.
- In another embodiment, the present invention provides a blade comprising a support, a first set of teeth comprising a flat tip attached to the support, a second set of at least four teeth comprising a sharp tip attached to the support, and a third set of at least four teeth comprising a sharp tip attached to the support. The first set of teeth is positioned between the second set teeth and the third set of teeth.
- In an alternative embodiment, the present invention provides an assembly comprising a taping applicator comprising a blade holder and a blade attached to the blade holder of the taping applicator. The blade comprises a support and a plurality of teeth attached to the support. One or more of the plurality of teeth defines a sharp tip, and one or more of the plurality of teeth defines a flat tip.
- The taping applicator can be any suitable taping applicator known by the skilled artisan that is compatible with the blade of the present invention. Representative non-limiting examples of the taping applicator are the Model PTA/T-627-2 Protective Tape Applicator, the Model T-626 Heavy-duty Flat Surface Tape Applicator, the Model T-627 Flat Surface Tape Applicator, the Model RSA-1 Round Surface Tape Applicator and the Model SD-625 Pressure Sensitive Tape Pad Applicator by Straub Design Company.
- In another aspect, the present invention provides an assembly comprising a bag sealing machine comprising a blade holder incorporated into the bag sealing machine and a blade attached to the blade holder of the bag sealing machine. The blade comprises a support and a plurality of teeth attached to the support. One or more of the plurality of teeth defines a sharp tip, and one or more of the plurality of teeth defines a flat tip. In one embodiment, the bag sealing machine is a TFT machine. In one embodiment, the bag sealing machine contains an assembly comprising a taping applicator that comprises the blade. In a preferred embodiment, the assembly is a TFT machine containing a taping applicator comprising the blade.
- The bag sealing machine and TFT machine can be any suitable machine known by the skilled artisan that is compatible with the blade of the present invention. For example, the TFT machine can trim, fold, and tape shut packages, bags, or other containers to provide a sturdy, roughed seal on the packaging material. A representative non-limiting example of a TFT machine is the TFT bag sealer manufactured by Doboy, Inc, well known in the art.
- In still another embodiment, the present invention provides a method for cutting a material. The method comprises providing a blade comprising a support and a plurality of teeth attached to the support, wherein at least one of the plurality of teeth defines a sharp tip and at least one of the plurality of teeth defines a flat tip. The method further comprises cutting the material with the blade.
- The blade can be incorporated as part of a taping applicator. Alternatively, the blade can be incorporated as part of a TFT bag sealing machine or a taping application in a TFT bag sealing machine.
- The material can comprise any suitable tape or labels. For example, the material can comprise a polypropylene tape.
- In an alternative embodiment, the present invention provides a method for sealing a container such as a bag or a package. The method comprises providing a blade comprising a support and a plurality of teeth attached to the support. At least one of the plurality of teeth defines a sharp tip and at least one of the plurality of teeth defines a flat tip. The blade is incorporated into a blade holder of a bag sealing machine, including a TFT machine or a taping applicator in a TFT machine.
- A bag is placed in the bag sealing machine, including a TFT bag machine. A tape is attached to a portion of the bag to seal off the bag. For example, the tape can be attached to a folded opening portion of the bag. Any suitable tape for sealing the bag can be used.
- Finally, the tape can be cut with the blade. For instance, the tape can be part of a roll, and the blade cuts the tape from the roll. The blade can also be used to cut off any loose ends of the tape extending from the bag.
- By way of example and not limitation, the following examples are illustrative of various embodiments of the invention.
- The development of the blade design of the present invention was a result of testing using standard knives including straight cut, perforated cut, guillotine cut, spear cut and finally an embodiment of the blade design of the present invention. Testing with the straight cut knife either did not cut the tape or cut it consistently. This led to jamming of the tape head and inconsistent placement on the package. The perforated knife cut and placed the tape consistently on the package, but the perforations left in the tape end led to premature opening of the package by allowing the tape to propagate (tear). Further testing using the guillotine and spear cut knife led to the same results achieved by using the straight cut knife, e.g., inconsistent tape placement and ragged cutting including machine jamming. This testing led to the development and design of the blade of the present invention that overcame all these issues as well as guaranteed accurate tape placement and stopped tape propagation (tearing). Basically, only the inventive blade cuts the tape in a manner that prevents tearing and premature bag opening (and spillage of the product in the bag).
- A blade was made from a piece of steel blade stock having the following dimensions: 2.50″ wide×1.62″ high×0.0650″ thick. The blade had 23 full teeth centered and 2 half teeth (one on each edge) across the 2.50″ side. The center 15 teeth were milled to provide a flat area, for example, by removing 0.12″ of material reducing the width to 1.50″. The remaining 8 full teeth and two half teeth were equally divided to have 4 full teeth and one half tooth per side of the blade. The blade was used as the cutting blade in a bag sealing machine. Bags of dog food were made and tested for integrity by handling the bags in a manner consistent with transportation, storage, retail, and home use conditions for such products. None of the bags tested experienced a premature tear in the tape used to seal the bag. Similar tests were performed on bags made using standard knives, i.e., a straight cut, perforated cut, guillotine cut, spear cut blade. Tape applied using standard knives or blades did not provide a reliable seal strong enough to prevent tearing and opening of the bag at the seal fold area due to propagation. The results show that the blade of the present invention cuts tape in a manner that essentially prevents tape tearing the bags, particularly due to propagation tears.
- The blades in embodiments of the present invention were used for cutting a 2″ wide polypropylene tape as part of a tape cutting assembly (e.g., a bag sealing machine). The blade design as described allows for tape tracking variability of ¼″ in either direction, whereby at any time during the tape cutting process at least one of the 4½ teeth on both sides will contact the tape and initiate the cut and break. Several pieces of tape were cut and applied to bags for packaging dog food. The bags were filled with dog food and tested for seal integrity. The tape applied and cut with the present inventive blade did not tear when the bags were handled in simulated industrial conditions.
- It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
